Press OK.
Line 2 selected appears briefly and the number 2 appears in the
display’s upper left corner.
If you use two phone lines, you may be given a voice mailbox number for
each line so you will need to save each phone line’s voice mailbox number
separately.
To do this, follow steps 1 and 2 above and select the outgoing line. Then,
refer to “Save the voice mailbox number” on page 64. Repeat the steps
above to select the other line and save its voice mailbox number.
